PERATING- DEVICE FDR EXPANDI'NG-PLUGS.

replication filed September l, 1915.

lo all whom fr', may concernf Be it known that L HARRY KAYFETZ.. a citizen of thc United Statee, and a resident or the city ot New York, borough of Brook lyn, in the county of Kings and State ot" New York. have invented a new and. Improved Operating' Device for Expandingilugs, of which the following is a full, clear, and exact description.

ri`he invention relates to expanding plugs formed ot' a iuoher cylinder interposed between two washers adapted to he pressed toward. each other to expnnd the cylinder against the inner surface ot a pipe on which the plug' is to he need.

The ohieet of the invention is to provide a. new ane improved. ope atingr device more especially designed for panding a plug in. the pipe leading;` to a sewer to permit et' inaking' a house test ot' the plumbing, and an ranged to permit the plni'nher to couveniently place the operating device in position logged fr with the plug and to act-nate the operating device a view to expand the plugJ hy means e.. pipe.

ln order to acconii'ilinh the desired result use is made of a trarne adapted to he renifnahlj: attached to the uut) ot' the pipe in which the plug i.: to he expandedT and a ninnnaly controlled epm-:inning device mounted on the Sai-1l 'traine and extendingr through 'the said hun into the pd to enga ge the actuating; i'nen'ililer of he plug.

A practical einlioriinient of the invention reprenentcrl in the aeeomimnying draufines forming a part of this specification in which similar' fzl'iaraetorf. ol reference inelicate correaiiondiug parts in both viewn.

and is adapted to be connected with a source of Water supply to allow of testing the plumbing h v forcing water into the pipe 11 and into the various pipes connected with the saine. The Sprocket wheel nut 19 is engaged by the lower end ot' a sprocket chain also passing around a sprocket wheel 22 seeure-:l on the shaft 23 journaled in suitable hearings 24 attached to the top 25 of a frame having a double arm 2G depending from the top and engaging the interior ot' the huh 12. Clamping' pieces 9,7 engage the exterior of the hul) 1i), and the sitlememhers of the arm 2G, and screws 2S pas'n through the said clampingr meinliers '2T and Screw in the Side niernliers oi' the ain: 2G to securely clamp the frame in place. "ilo lop is preferably in the form of a fork 29 straddlinf; the supply pipe 1S and resting on top ot' a elecve 30 which in turn rests on a collar 31 clamped to the supply pipe 1h liv a screw 82 on which is held a depending arm 'l in which screws a Soreny $2.4 engaging a (-lanipiug nenilier 35 fitting exteriorlv on the huh 12 so as to forni a very rigid support in conjunction with the traine previously mentioned Yfor Slrpporting the operating device exteriorly on the hul 12 of tho pipe 1l` The shaft fl is provided with polygonal terminals flo, either oi which i.-; :adapted to ne cngafed h v a ratchet wrench il? .it usual Construction for turning' the shaft 23 with a view lo rotate thel sprocket wheel 32 in either a Vforward or reverse direction.

The operation is as follows: The pipe 18 Iwith the unexpanded plug l() thereon een he readily lowered into the pipe l1 by way oi' the hul) l2, and then the framework including,r the collar ll and arm are fuetened in position on the huh 12` after which the operator applies the ratchet wrench 2S? to ono of the polygonal ends fit', of the Shaft 23 to rotate the said shaft in one direction. When thil takes place atraveling motion is given to the sprocket chain il whereby the latter rotates the wheel nut l) and srzrows; theI Same forward on the threaded end 1i' ol thi pipo 1S. This forward movenient of the wheel nut lil (faufes :i like movement of the movalile washer lf3 so that the ring or cylinder 14 is pressed and exianded against the inner surface of the pipe to close the nanna lVater is now passed through the pipe lvl' under pressure to test the pllunlii gg evstoni in the house in the usual manner. Alter the teint han lieon made, the ielat ful reverses the ratchet wreneh 37 of the shaft "lil to rotate the latter in the reverSe direction with a vieu' to turn the wheel nntli) in a reverse direction to release the rubber ring or i: vlinder 1l. The "rameu'orlt is then detached from the hub 12 to permit of conveniently removingr the operating deviee and the plug l() from the pipe 1l by \va v of the hub l'l. ln order to prevent splashing of the outlowing water into the operator`s face vwhen releasing the rubber ring r cylinder 1l. use is made ot' a bag or piece of canvas vor the like, plm-ed over the operating def vice while the\operat r turns the shaft 23 in a reverie direetion.

The operating device shown and described very simple and durable in construction and enables a plumber or other person to readily apply the same to the pipe 11 and to operate the. same. at a point remote from the pipe. lt nill also lie notieed that by the use of the operating device the hub l2 or the pipe ll is not liable to be injured, which in common b v the n `ans non' employed for aetuating the exparuling plug 10.
